Hopefully I'll have a chance to follow it in the future.

Great thread Andy, excellent work. I'm planning to extract all of your posts and pictures and compile them into a pdf document so people can print it out and use it as a garage reference. Would you have any objections to me doing this?

Cheers for your efforts in documenting your work.

Thanks for the nice comment...But I want this info to be exclusive to the forum please. It was done so that people on this forum could reference it when building engines. It is not a professional guide and should not be used or offered as such.. There are lots of books and videos out there on engine building for anyone who wants a proper guide. 

 

Thanks.

Looks tidy....hope it all goes well!

Brilliant thread thanks.
In relation to the addition of the adjustable cam sprocket timing gear, are there any alignment issues or do you just bolt them on.
Cheers?

[AndyMiniMad.]

Thanks Scoop77, The duplex timing gear simply slots over the existing woodruff keys in the crank and cam. They go on dot to dot and are then adjusted by undoing the Hex bolts.

Lovely thanks ;)

Andy thanks so much for this! Quick question and it'll probably sound awfully obvious but how do you recommend stripping and repainting the block and head?

I used a parts washer to get all the grease and old oil off then a wire brush on the drill to remove all the old paint. then back into the parts washer for a really good scrub. you really need the oil plugs and core plugs removed to get the gallery's totally flushed out. Lastly once its completely dry, I blast everything with the air hose to remove any lingering bits if grit or dirt. Once the paint is on and dry you need to clean it all again. time consuming I know. but well worth the effort. Finally I oil everything up before the assembly starts!!

Good luck and thanks for reading.

Apart from cleaning the inside of the breather out, is there a benefit of modifying the breather? I'm assuming it's for clearance, but what's it for clearance of?
